Abstract

conjunto de detentor selecionável com proteção neutra. um conjunto de detentor selecionável que tem um alojamento com uma pluralidade de passagens. dentro do alojamento está um carretel seletor, que é disposto dentro de uma passagem seletora, e o qual é giratório para prover uma pluralidade de posições rotacionais incluindo uma posição não detentora, uma posição de movimento para abaixo, e uma posição de detentor contínuo. uma válvula de verificação piloto é disposta dentro do alojamento e provê um caminho de fluxo de fluido a partir de uma passagem piloto até uma passagem seletora e uma passagem detentora. um pistão de armar detentor é disposto dentro da passagem detentora e é conectado a um carretel de válvula de controle direcional. desse modo, dependendo da posição rotacional do carretel seletor, o carretel seletor pode ou prover um caminho de fluxo contínuo através da passagem seletora até um tanque, um caminho de fluxo que é controlado pela posição axial do carretel seletor, ou impedir o fluxo para o tanque para operar o pistão de armar detentor.Selectable holder set with neutral protection. a set of selectable keeper that has a housing with a plurality of passages. inside the housing is a selector reel, which is arranged within a selector passage, and which is rotatable to provide a plurality of rotational positions including a non-holding position, a downward moving position, and a continuous holding position. a pilot check valve is arranged inside the housing and provides a fluid flow path from a pilot passage to a selector passage and a detent passage. a detent cocking piston is disposed within the detent passage and is connected to a directional control valve spool. therefore, depending on the rotational position of the selector, the selector can either provide a continuous flow path through the selector passage to a tank, a flow path that is controlled by the axial position of the selector, or prevent flow to the tank to operate the detent cocking piston.
